Care Management in Scientific Production in Integrative Oncology in Latin America: An Integrative Review

Introduction: Including traditional, complementary and integrative medicines in national health systems is a point of discussion worldwide. This article focuses on the theme within the scope of oncology in Latin America. Objective: To analyze the health care management dimensions included in scientific production in integrative oncology in Latin America. Materials and method: This is an integrative literature review carried out in the LILACS, Mosaico, IBECS, PubMed and Embase databases, whose guiding question was prepared according to The PRISMA 2020 Statement recommendations. The search occurred by the association of free terms related to the descriptors "Integrative Oncology," "Complementary Therapies," "Health Care," "Care Management," and "Countries That Make Up Latin America." Data were interpreted from the conceptual perspective of health care management dimensions. Results: The study selection process identified 206 studies. The final sample was made up of eight articles available online in full, published between 2017 and 2022 in Portuguese, Spanish or English. Articles were developed in Brazil (n = 4), Chile, Colombia, Peru, and Uruguay (n = 1, respectively). There was a predominance of the individual health care management dimension as the focus of analyzed studies. The "professional," "family," "societal," and "organizational" dimensions were presented in the discussion of results. Conclusions: Despite the insufficiency of studies, analysis of interdependence between dimensions indicates the complexity of the management process for integrating traditional, complementary and integrative medicine in oncological care in Latin America, which suggests an epistemology in the construction process.

Evolução da mortalidade por neoplasias entre os anos de 2010 a 2020 no Brasil segundo sexo e localização primária do tumor / Evolution of mortality from neoplasms between the years 2010 to 2020 in Brazil according to gender and primary location of the tumour

Introdução: o câncer é um grave problema de saúde pública, considerado a segunda causa de óbitos no Brasil. Devido à sua relevância, é indispensável um controle eficiente dos casos através do acompanhamento da taxa de mortalidade. Dessa forma, o trabalho analisou a evolução da mortalidade por câncer para as localizações primárias mais frequentes, segundo sexo, durante o período de 2010 a 2020. Metodologia: trata-se de um estudo observacional descritivo, no qual os dados foram obtidos através do Atlas On-line de Mortalidade por Câncer. Os dados colhidos correspondem ao número de óbitos estratificados por tipo de câncer mais frequente, por ano estudado e por sexo, além das taxas de mortalidade específica bruta e a taxa de mortalidade ajustada por idade para o sexo masculino e feminino, para cada tipo de câncer em estudo, considerando a população padrão mundial, sendo avaliado por regressão linear a significância da tendência temporal. Resultados: no Brasil, no período de 2010 a 2020, as neoplasias mais frequentes em mulheres foram câncer de mama, câncer nos brônquios e pulmões, câncer no colo do útero, câncer no cólon e no pâncreas e em homens foram brônquios e pulmões, câncer de próstata, câncer de estômago, de esôfago e no fígado e vias biliares, sendo observado uma tendência crescente na taxa de mortalidade em mulheres e decrescente na taxa de mortalidade em homens. Conclusão: os resultados demonstram um possível comprometimento com a notificação durante o período de pandemia por Covid-19 e um possível rastreamento ainda deficiente de câncer na população masculina.

Introduction: cancer is a severe public health problem, considered the second cause of death in Brazil. Due to its relevance, efficient control of cases by monitoring the mortality rate is essential. Thus, the work analysed the evolution of cancer mortality for the most frequent primary locations, according to sex, from 2010 to 2020. Methodology: this is a descriptive observational study in which data were obtained through the Atlas Online Cancer Mortality Report. The data collected correspond to the number of deaths stratified by the most frequent type of cancer, by year studied and by sex, in addition to the crude specific mortality rates and the age-adjusted mortality rate for males and females, for each type of cancer. Understudy, considering the standard world population, the significance of the temporal trend is evaluated by linear regression. Results: in Brazil, from 2010 to 2020, the most frequent neoplasms in women were breast cancer, bronchial and lung cancer, cervical cancer, colon and pancreas cancer and in men, they were bronchial and lung cancer, cancer prostate, stomach, oesophagal and liver and biliary tract cancer, with an increasing trend in the mortality rate in women and a decreasing trend in the mortality rate in men. Conclusion: the results demonstrate a possible compromise with notification during the Covid-19 pandemic and a possible still poor screening of cancer in the male population.

Is the use of Lactobacillus reuteri probiotic efficient as adjunctive therapy in the treatment of periodontitis? A systematic review / O uso do probiótico Lactobacillus reuteri como terapia adjuvante no tratamento da periodontite é eficaz? Uma revisão sistemática

Introdução: Pacientes com câncer apresentam uma tendência à perda ponderal e à desnutrição energético-proteica. Isso ocorre em razão das modificações que o organismo sofre pelo desenvolvimento da doença e pelos efeitos adversos do tratamento oncológico que contribuem para a redução da ingestão alimentar. Objetivo: Identificar evidências disponíveis na literatura científica sobre a ingestão alimentar de mulheres com tumores ginecológicos em tratamento oncológico. Método: Revisão integrativa da literatura cujas buscas foram realizadas nas bases de dados Embase, MEDLINE e LILACS por meio da associação de termos descritores e palavras livres. Foram incluídos nas análises estudos observacionais que avaliaram a ingestão alimentar de mulheres adultas com tumores ginecológicos durante o tratamento oncológico, redigidos em português, inglês e espanhol. Resultados: Esta revisão analisou seis estudos que investigaram a mudança na ingestão alimentar dessa população. Identificou-se uma redução da ingestão em até 31% de energia, 39,9% de proteínas, 33,7% de lipídeos, 28,7% de carboidratos e uma inadequação da ingestão de determinados micronutrientes. Conclusão: Mulheres com tumores ginecológicos durante o tratamento oncológico apresentam redução significativa da ingestão de energia, proteínas, lipídeos, carboidratos e micronutrientes. Considerando que a perda de peso e a desnutrição em pacientes com câncer está associada a desfechos clínicos negativos, a avaliação e a análise da ingestão alimentar desses indivíduos são fundamentais para possibilitar uma intervenção nutricional precoce, boa resposta ao tratamento e consequente melhoria da qualidade de vida

Introduction: Cancer patients tend to lose weight and energy-protein malnutrition because of the changes the organism undergoes caused by the progression of the disease and treatment-related adverse effects that contribute for the reduction of food intake. Objective: To identify scientific literature-based evidences on food intake of women with gynecological tumors undergoing cancer treatment. Method: Integrative literature review through searches at the Embase, MEDLINE and LILACS databases with the association of descriptive terms and free words. Observational studies in Portuguese, English and Spanish that evaluated the food intake of this population were included in the analyzes. Results: This review identified 6 studies that investigated the change in food intake of women with gynecological cancer undergoing cancer treatment. A reduction in intake was identified in until 31% of energy, 39.9% of proteins, 33.7% of lipids, 28.7% of carbohydrates and inadequate intake of certain micronutrients. Conclusion: Women with gynecological tumors during cancer treatment present significant reduction of energy, proteins, lipids, carbohydrates and micronutrients intake. Considering that weight loss and malnutrition in cancer patients are associated with negative clinical outcomes, the evaluation and analysis of the food intake of this population individuals is essential for early nutritional intervention, good response to treatment and improvement of the quality of life

Effect of systemic antibiotic and probiotic therapies as adjuvant treatments of subgingival instrumentation for periodontitis: a randomized controlled clinical study

Abstract Objective: This study assessed the efficacy of two adjunct therapies (antibiotic and probiotic) for periodontal treatment based on clinical and immunological parameters in patients with Stage II and III Grade B periodontitis. Methodology: 45 patients were randomly allocated into three groups: control group (CG); antibiotic group (GAtb), in which 500 mg amoxicillin + 400 mg metronidazole were used; and probiotic group (GProb), for which Lactobacillus reuteri was used. Patients received medications after undergoing periodontal debridement. Clinical and immunological parameters were assessed at baseline, 30 days, and 90 days. Results: All therapies reduced bleeding on probing (BoP) in the evaluated periods, and the GAtb had a greater reduction at 90 days (p=0.03). The GProb group showed better results for plaque index (PI) and gingival recession (GR) compared to the GAtb at 90 days (p=0.0014; p=0.006). The area of inflammation (PISA Index) significantly decreased in all therapies in the evaluated periods. Therapies had no significant differences regarding moderate pockets. The GAtb had a greater reduction in probing depth (PD) for deep pockets (p=0.03) at 90 days and in the number of deep pocket sites at 30 days (p=0.04). The occurrence of adverse effects was commonly reported in the GAtb as a percentage per patient. The GAtb had a significant reduction in the concentration of interleukins IL-1β and IL-8 and an increase in IL-10 and TNF-α. The CG had a reduction in IL-6 and IL-1 β, whereas in the GProb there was no difference. Conclusion: After three months, none of the adjuvant therapies provided any additional benefit for subgingival instrumentation.

Frecuencia de ansiedad y depresión en pacientes coordinados para cirugía electiva en el Hospital de Clínicas Manuel Quintela / Frequency of anxiety and depression in patients coordinated for elective surgery at the Hospital de Clínicas Manuel Quintela

Los trastornos depresivos y de ansiedad son más frecuentes en pacientes que se encuentran a la espera de un acto anestésico-quirúrgico. Estos se consideran factores de riesgo de complicaciones posoperatorias de allí el interés de detectarlos en la consulta preoperatoria. El objetivo del trabajo fue determinar la frecuencia de ansiedad y depresión en pacientes pre-quirúrgicos en el Hospital de Clínicas utilizando la Escala de Ansiedad y Depresión Hospitalaria (Hospital Anxiety and Depression Scale) validada en español mediante un estudio observacional, descriptivo y transversal. Se realizó una encuesta a una muestra tomada al azar, de pacientes prequirúrgicos obtenida de la consulta externa o de las consultas provenientes de salas de internación quirúrgica del Hospital de Clínicas entre julio y septiembre de 2019. La prevalencia global de ansiedad y depresión fue de 44% y 14,5%, respectivamente. Un mayor nivel de depresión fue asociado al sexo femenino, no encontrándose asociación entre otras variables como edad, tipo de cirugía u hospitalización, y la mayor frecuencia de cualquiera de los trastornos. Se concluye que los niveles de ansiedad son relativamente elevados y, junto a la depresión, pueden ser detectados en la consulta preoperatoria de manera sencilla utilizando el instrumento propuesto.

The depressive and anxiety disorders are more frequent in patients who are waiting a surgical procedure. These are risk factors of postoperative complications. The objective of this work was to determine the incidence of anxiety and depression in the preoperative period at the University Hospital using the Hospital Anxiety and Depression Scale validated in spanish through an observational, descriptive and cross-sectional study. A socio-demographic characterization of patients was carried out and aspects related to imminent surgery were described. The study was conducted in a random sample of pre-surgical patients who attended an outpatient clinic or were hospitalized at the Hospital de Clínicas, between July and September 2019. The global incidence of anxiety and depression was 44% and 14.5% respectively. A mayor level of depression was observed in females, no other statistically significant evidence was found to support an association between the other variables (age, type of surgery, hospitalization) and the higher prevalence of any of the disorders. We concluded that the level of anxiety is high in our population and deserves to be detected, through the implementation of a simple instrument.

Surveillance of hemorrhagic fever and/or neuroinvasive disease: challenges of diagnosis

ABSTRACT OBJECTIVE To evaluate the performance of post mortem laboratory analysis in identifying the causes of hemorrhagic fever and/or neuroinvasive disease in deaths by arbovirus infection. METHODS Retrospective cross-sectional study based on the differential analysis and final outcome obtained in patients whose samples underwent laboratory testing for arboviruses at the Pathology Center of the Adolfo Lutz Institute, in São Paulo, Brazil. RESULTS Of the 1355 adults clinically diagnosed with hemorrhagic fever and/or neuroinvasive disease, the most commonly attributed cause of death and the most common final outcome was dengue fever. Almost half of the samples tested negative on all laboratory tests conducted. CONCLUSION The failure to identify the causative agent in a great number of cases highlights a gap in the diagnosis of deaths of unknown etiology. Additional immunohistochemical and molecular assessments need to be added to the post-mortem protocol if all laboratory evaluations performed fail to identify a causative agent. While part of our findings may be due to technical issues related to sample fixation, better information availability when making the initial diagnosis is crucial. Including molecular approaches might lead to a significant advancement in diagnostic accuracy.

Presença da mutação do gene BRCA1 em cadelas com tumores mamários malignos / Presence of BRCA1 gene mutation in bitches with malignant mammary tumors

Mammary tumors (MTs) in bitches are similar to breast cancers in women. Thus, they can be used as a model for human breast cancer and findings can be extrapolated for use in human medicine. BRCA1 is a tumor suppressor gene. When the gene has a mutation, it cannot repair damaged DNA, which causes genetic instability and tumorigenesis. Therefore, we aimed to study the frequency of single nucleotide polymorphisms (SNPs) in the BRCA1 gene that are associated with distinct histological types of malignant MT in bitches. The study population consisted of 91 bitches, including a control group of 6 animals with healthy mammary glands and 85 animals with MTs. All animals underwent a presurgery evaluation consisting of a questionnaire administered to the person responsible for the animal, a physical examination, collection of peripheral blood for hematological and serum biochemistry evaluations, an electrocardiogram, and a preanesthesia evaluation. In addition, distant metastasis was studied via chest radiography and abdominal ultrasound. After evaluations were complete, the animals that could undergo surgery were administered general anesthesia and underwent a mastectomy or mammary gland sample collection. Histopathological examination and molecular analysis were performed to identify mutations in the BRCA1 gene. Histopathological examinations found 10 different types of malignant tumors in 36 sick animals. Tumor samples plus samples from the 6 control animals were subjected to DNA extraction, polymerase chain reaction (PCR) analysis, and genetic sequencing. The tumor with the highest incidence (33.33%) was a complex carcinoma, followed by carcinoma in mixed tumor (13.88), tubular carcinoma (13.88) and carcinosarcoma (13.88). Molecular analysis revealed 3 different SNP points in 5 samples (4006G>A, 3619A>G, and 3761C>T). The allelic variant 4006G>A (1/36) resulted in the alteration of the amino acid valine by isoleucine (V1336 I). The mutation 3619A>G (2/36) inserted the amino acid alanine instead of threonine (T1207 A). The mutation 3761C>T (2/36) led to the alteration of the amino acid serine by phenylalanine (S1254 F), a mutation for which there are no published reports. The histological types that showed BRCA1 mutations were complex carcinoma (1/5), carcinoma in mixed tumor (1/5), papillary carcinoma (1/5) and tubular carcinoma (2/5). Software analysis identified the new SNP (nucleotide 3761) in BRCA1 and 2 point mutations in nucleotides 4006 and 3619 and responsible for genetic instability. The development of breast cancer is caused by many endogenous and exogenous factors. The results of our study show that these factors have a greater presence in female, mixed breed, uncastrated, and older dogs, confirming the data in the veterinary literature. In the present study, we found different histological types of malignant breast tumors with mutations in the BRCA1 gene, as other authors have reported. However, we also found the mutation 3761C>T, which, to the best of our knowledge, has not been reported in the literature. This shows the need for studies in veterinary medicine that assess mutations in the BRCA1 gene and the most common histological types. In conclusion, SNPs in the BRCA1 gene cause genetic instability, resulting in additional mutations that lead to the development of breast tumors. They are point mutations that affect transcription, resulting in truncated proteins. These proteins may have a loss of function, leading to carcinogenesis.(AU)

Efeito da estimulação elétrica no processo de reparação de tecido mole no palato: estudo em camundongos / Effect of electrical stimulation on soft tissue repair process at the palate: a study in mice

A estimulação elétrica (EE) tem sido usada no tratamento de lesões crônicas apresentando resultados favoráveis no fechamento da lesão cutânea entre outras aplicações clínicas. No entanto, a literatura carece de estudos avaliando se os efeitos da EE no fechamento da lesão oral. Diante disso, torna-se relevante investigar os efeitos da EE durante o processo de reparo da lesão oral em camundongos (Swiss). Métodos: Noventa animais foram divididos em grupos: Controle (C; n=45) que receberam a aplicação da EE com o aparelho desligado e Teste (EE; n=45) que receberam a EE (100 µA; 9 kHz; 660 mVpp; 1x/dia por 3 dias). Uma lesão de espessura total foi realizada com punch de biópsia de 1,5 mm de diâmetro. Os animais foram eutanasiados no 1o, 3o e 5o dia após a confecção da lesão. As amostras foram fixadas em paraformaldeído 4%, descalcificadas em ácido fórmico 20% e emblocadas em parafina. Os parâmetros avaliados foram: fechamento clínico da lesão; distância de reparação epitelial (DRE) e conjuntiva (DRC), concentração de citocinas IL-1ß, IL-6, IL-8, IL-10, TNF-α e VEGF; porcentagem de fibras colágenas e quantificação das proteínas de sinalização Smad2. Resultados: A área de fechamento clínico foi reduzida no grupo EE no 5º dia de avaliação (p=0,01). As DRE e DRC do grupo EE apresentaram menor distância em todos os tempos avaliados (p<0,05) com reduzida concentração de IL-6, TNF-α, IL-10 e VEGF (p<0,05). Não houve diferença na porcentagem de fibras colágenas e na phospho-Smad2. Conclusão: A EE teve efeito positivo nos parâmetros clínicos e histológicos com modulação da resposta inflamatória no início do processo de reparo da lesão(AU)

Background: Since Electrical Stimulation (ES) has used for chronic wounds treatment and other clinical applications showing favorable results in wound closure, it was hypothesized whether it could bring good results in oral wound closure. The aim was to investigate the ES effects during the oral wound healing process in mice (Swiss). Methods: Ninety animals were divided in groups: Control (C; n=45) which received a fictitious ES application, i.e. the ES applicance was shutted off and ES (ES; n=45) which received ES (100 µA; 9 kHz; 660 mVpp) once time a day for 3 days consecutively. A full thickness wound was done using a 1.5 mm diameter biopsy punch in the hard palate. The animals were euthanized on 1st, 3rd and 5th day post-wounding. The samples were fixed, decalcified and embedded in paraffin. The parameters evaluated were: clinical wound closure; distance of epithelial and connective wound edges (EWD and CWD); cytokines (IL-1ß, IL-6, IL-8, IL-10), TNF-α and VEGF by multiplex, percentage of collagen fibers and Smad proteins. Results: Clinical wound closure area was reduced on day 5 in ES group (p = 0.01). Both EWD and CWD distance were shorter in all times (p < 0.05) with a reduction of inflammatory cytokines production (p < 0.05). There were no difference in collagen percentage and phospho-Smad2. Conclusion: ES had a positive effect on clinical and histomorphometric wound closure outcomes showing a modulation of inflammatory response in the beginning of wound healing(AU)

Effect of two corticotomy protocols on periodontal tissue and orthodontic movement

Abstract Objective To compare two corticotomy surgical protocols in rats to verify whether they alter conventional orthodontic movement. Methodology Sixty Wistar rats were divided into three groups - orthodontic movement (CG), orthodontic movement and corticotomy (G1) and orthodontic movement with corticotomy and decortication (G2) - and euthanized after 7 and 14 days. Tooth movement (mm), bone volume fraction and bone volume ratio to total volume (BV/TV), and bone mineral density (BMD) were evaluated by micro-CT. The total amount of bone was measured in square millimeters and expressed as the percentage of bone area in the histomorphometry. The number of positive TRAP cells and RANK/RANKL/OPG interaction were also investigated. Results Day 14 showed a statistically significant difference in orthodontic tooth movement in CG compared with G1 (7.52 mm; p=0.009) and G2 (7.36 mm; p=0.016). A micro-CT analysis revealed a difference between CG, G1 and G2 regarding BV/TV, with G1 and G2 presenting a lower BV/TV ratio at 14 days (0.77 and 0.73 respectively); we found no statistically significant differences regarding BMD. There was a difference in the total amount of bone in the CG group between 7 and 14 days. At 14 days, CG presented a significantly higher bone percentage than G1 and G2. Regarding TRAP, G2 had more positive cells at 7 and 14 days compared with CG and G1. Conclusion Corticotomy accelerates orthodontic movement. Decortication does not improve corticotomy efficiency.

Charcterization of feeding of children under 24 months in units cared by the family health strategy / Caracterização da alimentação de crianças menores de 24 meses em unidades da estratégia saúde da família

ABSTRACT Objective: To describe the median age of introduction and regular food intake by young children in units of the Family Health Strategy. Methods: Cross-sectional study with 283 young children chosen by uniform stratified cluster sampling. Socio-demographic data on the mother and the child's food intake were collected (age of food introduction and weekly frequency). Foods were grouped into in natura/minimally processed (G1); culinary ingredients (G2); processed (G3) and ultra-processed (G4). The survival analysis was applied to define the median age of food introduction and the chi-square test was used to compare the frequency of food intake, according to the age range (0-5.9; 6-11.9; and 12-23.9 months old). Results: The median duration of exclusive breastfeeding and breastfeeding were three and 19 months, respectively. The age of median food introduction of G1 was six months, except for eggs, milk and coffee (12 months). For oil and salt (G2), the median was 6 months, and for sugar (G2), seven months. The median age of introduction of most food of G4 was 12 months; for infant formulas, it was seven months; cookies and baby food, eight months. Most food had not yet been introduced for children under six months old. For children from six to 11.9 months old, the regular consumption of G4 (≥5 days/week) was higher for cookies (23.8%), bread (21.2%), infant formulas (21.2%) and baby food (35%); and for children from 12 to 23.9 months old, it was higher for cookies (31.2%), bread (57.5%) and baby food (48.7%). Conclusions: Food introduced and consumed on a regular basis was mainly in natura, at all ages. Processed and ultra-processed food presented a higher frequency of consumption after 12 months old.

Alimentos processados e ultraprocessados apresentaram maior frequência de consumo após os 12 meses.

Seed systems of Brachiaria species in intercropping with grain sorghum in the off-season / Sistemas de implantação de espécies de Brachiaria em consórcio com sorgo granífero na segunda safra

The grain sorghum intercropped with Brachiaria provides the production of grains and dry mass in the off-season; however, there is a lack of information related to the implantation of these species. The objective of this study was to identify the best association of sorghum and Brachiaria in the production of grain and dry matter in the Brazilian Cerrado region. The experiment was conducted in Rio Verde, State of Goiás, in the experimental design of randomized blocks, in a 2×3×4+5 factorial scheme, with four replications. Two sorghum hybrids (BRS 330 and DKB 551) associated to three Brachiaria species (Brachiaria brizantha cultivar Marandu, Brachiaria decumbens and Brachiaria ruziziensis) were evaluated in four systems of Brachiaria implantation (row, interrow, row + interrow of sorghum and spread). Additional treatments referred to the two sorghum monocrops and the three Brachiaria species. The sorghum and Brachiaria consortium resulted in a reduction in grain yield, but the Brachiaria implantation systems in the row, interrow and spread were the most promising. The sorghum hybrid DKB 551 was the most sensitive to the competition with Brachiaria, although there were no grain yield differences in the intercropping. The Brachiaria intercropped in the interrow and in the row + interrow, mainly with B. ruziziensis, were the most promising for the production of dry mass and total crude protein. The cultivation of Brachiaria intercropped with sorghum provided a greater contribution of dry mass in the off-season, an important fact for the no-tillage system in the agricultural production systems of the Brazilian Cerrado.(AU)

O consórcio de sorgo granífero com braquiária proporciona a produção de grãos e massa seca na entressafra; contudo, há carência de informações relacionadas à implantação dessas espécies. Sendo assim, este trabalho teve por objetivo identificar a melhor associação de sorgo granífero e braquiária na segunda safra para produção de grãos e massa seca na região do Cerrado. O experimento foi conduzido em Rio Verde, Goiás, no delineamento experimental de blocos randomizados, em esquema fatorial 2×3×4+5, com quatro repetições. Foram avaliados dois híbridos de sorgo granífero (BRS 330 e DKB 551) associados a três espécies de Brachiaria (Brachiaria brizantha cultivar Marandu, Brachiaria decumbens e Brachiaria ruziziensis) em quatro sistemas de implantação da braquiária (linha, entrelinha, linha + entrelinha do sorgo e a lanço). Os tratamentos adicionais referiam-se aos dois monocultivos de sorgo e às três espécies de braquiária. O consórcio de sorgo com braquiária ocasionou redução no rendimento de grãos, porém os sistemas de implantação da braquiária na linha, entrelinha e a lanço foram os mais promissores. O híbrido de sorgo DKB 551 foi o mais sensível à competição com a braquiária, sem, contudo, haver diferenças de rendimento de grãos em consórcio. Os consórcios das braquiárias na entrelinha e na linha + entrelinha, principalmente com a B. ruziziensis, foram os mais promissores para produção de massa seca e proteína bruta total. O cultivo de braquiária com o sorgo proporcionou maior aporte de massa seca na entressafra, fato importante para o sistema de plantio direto nos sistemas de produção agrícola dos Cerrados.(AU)

Demência rapidamente progressiva por linfoma primário do sistema nervoso central: um relato de caso / Rapidly progressive dementia due to primary central nervous system lymphoma: a case report

As demências rapidamente progressivas são condições que impactam a vida do paciente, entretanto nem sempre são consideradas durante a investigação da síndrome demencial. Este relato descreve uma paciente portadora de artrite reumatoide em uso crônico de corticoterapia que evoluiu com um quadro de demência rapidamente progressiva no período de cinco meses. Durante a investigação, evidenciou-se o linfoma primário de sistema nervoso central como causa de sua síndrome demencial. Faz-se importante destacar que o uso prolongado de corticoide pode estar associado a um estado de imunossupressão, o que é fator de risco para o surgimento do linfoma de sistema nervoso central.

Rapidly progressive dementias are conditions that worsening the patient's life; however they are not always considered during the investigation of dementia syndrome. This report describes the case of a patient with rheumatoid arthritis and chronic use of corticosteroid therapy, who developed rapidly progressive dementia within 5 months. During the investigation, the primary lymphoma of the central nervous system was evidenced as the cause of its dementia syndrome. Importantly, prolonged use of corticosteroids may be associated with a state of immunosuppression, which is a risk factor for the onset of central nervous system lymphoma.

Consumption of minimally processed and ultra-processed foods among students from public and private schools / Consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada

ABSTRACT Objective: To compare and analyze the consumption of minimally processed and ultra-processed foods among students from public and private schools. Methods: Study conducted in Uberlândia, MG, with fifth-grade students from three private and six public schools, selected by stratified cluster sampling. We collected data on food consumption using the 24-hour recall. Foods were classified into four groups (G) according to extent and purpose of processing: fresh/minimally processed foods (G1) culinary ingredients (G2), processed foods (G3), and ultra-processed foods (G4). Total energy intake (kcal) of each group, amount of sugar (g), sodium (mg), and fiber (g) were quantified and compared according to administrative affiliation (private or public). Results: Percentage of total energy intake was: G1 - 52%; G2 - 12%; G3 - 5%; e G4 - 31%. Energy intake from G1 (53 vs. 47%), G2 (12 vs. 9%), and G3 (6.0 vs. 0.1%), and amount of sodium (3,293 vs. 2,724 mg) and fiber (23 vs. 18 g) were higher among students from public schools. Energy intake from G4 (36 vs. 28%) and amount of sugar (20 vs. 14%) were higher among students from private schools. The consumption of foods from G1 in the school environment was higher among students from public schools (40 vs. 9%). Conclusions: Foods from G1 represent the highest percentage of total energy intake, while those from G4 constitute a third of calories consumed. Processed juice, sandwich cookie, processed cake, and breakfast cereals are more frequent among private school students; snacks and juice powder are more common for students from public schools.

RESUMO Objetivo: Comparar e analisar o consumo de alimentos minimamente processados e ultraprocessados entre escolares das redes pública e privada. Métodos: Estudo realizado em Uberlândia, MG, com escolares do quinto ano do ensino fundamental em nove escolas (três privadas e seis públicas), selecionados por amostragem estratificada por conglomerado. O consumo alimentar foi analisado utilizando recordatório de 24 horas. Os alimentos foram classificados segundo extensão e propósito do seu processamento em quatro grupos (G): alimentos in natura/minimamente processados (G1), ingredientes culinários (G2), alimentos processados (G3) e ultraprocessados (G4). Os valores energéticos totais (kcal) provenientes de cada grupo, quantidade de açúcar (g), sódio (mg) e fibras (g) foram quantificados e comparados segundo dependência administrativa. Resultados: O consumo de energia foi: G1, 52%; G2, 12%; G3, 5%; e G4, 31%. Os valores energéticos provenientes de G1 (53 vs. 47%), G2 (12 vs. 9%) e G3 (6,0 vs. 0,1%), a quantidade de sódio (3.293 vs. 2.724 mg) e a de fibras (23 vs. 18 g) foram superiores em escolares da rede pública. O valor percentual energético do G4 (36 vs. 28%) e a quantidade de açúcar (20 vs. 14%) foram superiores em escolares da rede privada. O consumo do G1 na escola foi superior nos escolares da rede pública (40 vs. 9%). Conclusões: Alimentos do G1 representam o maior percentual do valor energético total e do G4, um terço das calorias ingeridas. Suco pronto, biscoito recheado, bolo industrializado, cereais matinais são mais frequentes em escolares da rede privada e salgadinhos e suco em pó nos da rede pública.

The influence of LLLT applied on applied on calvarial defect in rats under effect of cigarette smoke

Abstract Objective Considering the global public health problem of smoking, which can negatively influence bone tissue repair, the aim of this study is to analyze the influence of photobiomodulation therapy (PBM) on calvaria defects created surgically in specimens under the effect of cigarette smoke and analyzed with use of histomorphometric and immunohistochemistry techniques. Methodology Calvaria defects 4.1 mm in diameter were surgically created in the calvaria of 90-day-old rats (n=60) that were randomly divided into 4 experimental groups containing 15 animals each: control group (C), smoking group (S), laser group (L), and smoke associated with laser group (S+L). The animals were subjected to surgery for calvaria defects and underwent PBM, being evaluated at 21, 45, and 60 days post-surgery. The specimens were then processed for histomorphometric and immunohistochemistry analyses. The area of bone neoformation (ABN), percentage of bone neoformation (PBNF), and the remaining distance between the edges of the defects (D) were analyzed histometrically. Quantitative analysis of the TRAP immunolabeled cells was also performed. The data were subjected to analysis of variance (ANOVA) in conjunction with Tukey's test to verify the statistical differences between groups (p<0.05). Results The smoking group showed less ABN compared to the other experimental groups in all periods, and it also showed more D at 21 days compared to the remaining groups and at 45 days compared to the laser group. The smoking group showed a lower PNBF compared to the laser group in all experimental periods and compared to smoking combined with LLLT group at 21 days. Conclusions PBM acted on bone biomodulation, thus stimulating new bone formation and compensating for the negative factor of smoking, which can be used as a supportive therapy during bone repair processes.

Cuidar de idosos: um assunto de mulher? / Caring for the elderly: a women's issue?

O gênero é considerado por muitos pesquisadores um fator que influencia a escolha do cuidador de idosos. Essa revisão narrativa visa refletir sobre a ação da cultura como agente determinante na escolha da mulher como responsável pelo cuidar. Este artigo preconiza a redefinição do critério de escolha dos cuidadores, de forma a estabelecer o papel de cuidar para o familiar mais apto a realizá-lo, não sendo o gênero o seu determinante. Espera-se reforçar a necessidade de desenvolvimento de políticas sociais direcionadas à mulher, considerando a sobrecarga que acomete o cuidador. Discute-se o valor social atribuído à atividade de cuidado e a importância de torná-la mais favorável a quem a exerce. Conclui-se que debater sobre a influência da cultura nessa atividade predominantemente feminina é uma tarefa ardilosa, porém necessária quando se visa melhorias para os envolvidos no contexto do cuidar (AU).

Gender is considered for many researchers a factor that influences the elderly's caregiver choice. This narrative review aims to reflect about the culture as determinant agent of woman's choice as responsible for caring. This article recommends a review of the criteria for choosing caregivers, in order to establish the role of caring to the family member that is more capable to accomplish it, not being genre its major determinant. We reinforce the need for developing social policies focusing on women, considering the burden that affects caregivers. It is discussed the social value attributed to caring activity and the importance of making it more favorable to caregivers. It is concluded that debating on the influence of culture on this predominantly female activity is a complex task, but necessary when it is aimed improvements for those involved in the context of caring (AU).

Chronic kidney disease and periodontal disease. Case report. / Doença renal crônica e tratamento periodontal. Relato de caso

Chronic renal disease promotes a decrease on kidneys filterability and nitrogen products accumulation on blood, electrolyte and system endocrine functions imbalance. Among the many clinical manifestations of chronic renal failure (CRF) in the oral cavity, there are: dry mouth, uremic stomatitis, radiographic changes in maxillary and jaw bones and accumulation of calculus on the teeth that increases levels of periodonto pathogenic microorganisms able to lead a periodontal tissue destruction and also have the potential to act from a distance on other organs, e.g. the kidneys. Thus, it becomes evident that a periodontal treatment of patients suffering from chronic renal failure is crucial for maintaining their general health conditions and a subsequent successful organ transplant.Thus, the objectives of this case report were to highlight how important the periodontal treatment is for chronic renal failure patients and to demonstrate improvements in their clinical condition through the treatment plan proposed herein. A patient with 43 years old carrier generalized moderate chronic periodontitis and CRF was submitted to scaling and root planning sessions, and later surgical access for scaling where the basic treatment not resulted in a resolution of the inflammatory periodontal process. The results obtained from a well-developed periodontal treatment and an effective cooperation of patient showed satisfactory results with periodontal disease process resolution or stabilization.Thus, periodontal treatment and patient compliance were crucial for the improvement of periodontal clinical conditions enabling a future successful renal transplantation.

A doença renal crônica promove uma redução na filtrabilidade dos rins e produtos nitrogenados acumulam no sangue promovendo um desequilíbrio eletrolítico e funcional do sistema endócrino. Dentre as diversas manifestações clínicas da doença renal crônica (DRC) na cavidade bucal estão: xerostomia, estomatite urêmica, alterações radiográficas nos ossos maxilares e mandibulares e acúmulo de cálculo dental que eleva os níveis de microrganismos periodontopatogênicos capazes de promover a destruição periodontal e também a capacidade de agir à distância em outros órgãos, como por exemplo, os rins. Dessa forma, torna-se evidente que o tratamento periodontal de pacientes que sofrem com a doença renal crônica é crucial para a manutenção de sua saúde geral e para o subsequente sucesso no transplante de órgão. Então, os objetivos deste relato de caso foram evidenciar a importância do tratamento periodontal para pacientes renais crônicos e demonstrar a melhora na condição clínica através do plano de tratamento proposto. Um paciente de 43 anos de idade, portador de periodontite crônica moderada generalizada e de DRC foi submetido às sessões de raspagem e alisamento radicular, e posteriormente, acesso cirúrgico para raspagem onde o tratamento básico não resultou na resolução do processo inflamatório periodontal. Os resultados obtidos a partir de um tratamento periodontal bem conduzido e uma efetiva cooperação do paciente mostraram resultados satisfatórios com a resolução ou estabilização da doença periodontal. Desta forma, o tratamento periodontal e a cooperação do paciente foram cruciais para a melhora das condições clínicas periodontais possibilitando um sucesso no futuro transplante renal. (AU)
